Title: Improvements in or relating to systems of receiving and indirectly amplifying radio frequency electrical oscillatory energy
IPC: H04B1/26
Filed: 1924-05-02
Abstract: 224,817. Jackson, W. J. Mellersh-, (Westinghouse Electric & Manufacturing Co.). May 2, 1924. Heterodyne receiving systems; thermionic heterodyne receivers.-Relates to self-heterodyne receiving systems in which supersonic beats are employed, as in Specification 137,271, and consists in using an harmonic of the local frequency for beating with the incoming oscillations. The self-heterodyne valve 8 has two tuned circuitsconnected to its grid, one circuit 4, 12 being tuned to the incoming wave and coupled to the aerial 1, the other circuit 13, 14 being coupled to a coil 15- in the plate circuit and tuned to a much lower frequency so that the second or higher harmonicdiffers from the received frequency by a readilyamplifiable supersonic frequency. Owing to the considerable difference in frequency between the two grid circuits their reaction on each other is reduced, and the local energy is not radiated. The supersonic beats are selected by a tuned plate circuit 18, 19 and are transferred through amplifiers 22 to a detector 23, the speech or other modulation of the..received waves being audible in the telephone 24 in the detector output circuit. When receiving unmodulated continuous waves, the supersonic currents after amplification are transferred to a self-heterodyne valve operating in the same manner as the valve 8, to produce audible beats in a telephone in its plate circuit. Further heterodyne stages may be employed.

Title: Treatment of diamonds
IPC: A44C17/04
Filed: 1955-04-18
Abstract: A method of treating a diamond having a yellow or brown colouration in order to reduce the colouration and cause the stone to appear more nearly white or bluish white, comprises irradiating the diamond with gamma rays of an energy exceeding 0.5 Mev.  The gamma rays may be produced by radioactive cobalt which is preferably enclosed in a metal tube which absorbs other radiation emitted.  The dose is preferably between 1.5 and 3 X 109 roentgens, and if the stones are over-exposed the excessive blue or blue-green colours may be reduced to some extent by heat treatment at about 450 DEG  C.  Better results may be obtained by using gamma rays of lower energy than those from cobalt, for example energies between 0.5 and 0.9 Mev.; these may be produced by bombarding a target with high-energy electrons, or by using a different radioactive material such as caesium.

Title: Improvements in or relating to screw propeller blades and the method of manufacturing same
IPC: B21D53/78
Filed: 1931-04-16
Abstract: 383,958. Making screw propellers. SQUIRES, J., The Terrace, Hagerstown, Maryland, U.S.A. April 16, 1931, No. 11280. [Classes 83 (ii) and 83 (iv).] Stamping.-A screw propeller blade is formed from a seamless tubular blank of uniform cross section by sizing the interior dimensions exactly, then sizing the exterior, spinning to close the tip end and finally spinning the blank into the desired aerofoil section of the blade. The tubular blank is formed with a shoulder 261 and is spun at the other end to tapered form 26 of thickened dimensions. The tip portion of the blank is dimensioned by a tapered reamer 27 and the inner surface of the main portion is dimensioned by a parallel reamer. The tube is then secured against a shoulder 5 and a die 32 is forced into the blank so as to expand it both radially and longitudinally, the tube being expanded beyond the elastic limit in this process. The blank is then placed on a mandrel and machined on the exterior surface, the root portion having an enlarged taper section 39 for engagement with the propeller hub. The blank is then placed in a spinning machine and the tip end closed by a spinning tool 44 and blow-lamp 43 being used for the purpose. The blank so formed is then heated in a furnace 45, it being suspended therein in a tube 46 from flanges 49. The inner tube 46 is closed by a plate 50 with a view to reducing circulation of air and oxidation. Oxidation may be further prevented by coating the blank with coal oil. The heated blank is then placed between dies having the inner surfaces of aerofoil section and so dimensioned that the circumferential dimension of the tube is equal to the perimeter of the aerofoil cross section. During this pressing operation the interior of the blank is subjected to high air pressure whereby it is kept in contact with the die surface. The dies may be heated and a normalizing process under heat and pressure may be adopted. After heating and quenching the blade is subjected to a nitriding process which involves heating to about 11000‹ F for several hours in the presence of a nitrogen gas such as ammonia. The blade is then buffed and polished and may be plated and is finally brought to a balanced condition against a standard blade.

Filed: 1916-08-12
Abstract: 107,289. British Thomson-Houston Co., (General Electric Co.) Aug. 12, 1916. Electro-magnetic switches for use in starting up electric motors and having a shunt closing coil and a series lock-out coil have an armature 27 on the contact arm 12 formed with inclined faces 28, 29, sc that, when the arm is first attracted by the closing electro-magnet 11, the meeting point 30 of the two faces comes against the core 15 and the pull on the two faces is balanced. During this movement the switch remains open, the lock-out coil 23 keeps the other end of the arm 12 against the non-magnetic stop 26 and a spring 20 between the arm and a fixed stop 22 is compressed. When the current in the system falls below a certain level, the spring overcomes the action of the lock out coil and moves the arm about the point 30 the pull on the two faces is thereby unbal@ and the switch is closed.
